Nature of the spin resonance mode in CeCoIn
Yu Song, Weiyi Wang, John S. Van Dyke +9
Spin-fluctuation-mediated unconventional superconductivity can emerge at the border of magnetism, featuring a superconducting order parameter that changes sign in momentum space. D…
Evidence for singular-phonon-induced nematic superconductivity in a topological superconductor candidate SrBiSe
Jinghui Wang, Kejing Ran, Shichao Li +11
Superconductivity mediated by phonons is typically conventional, exhibiting a momentum-independent s-wave pairing function, due to the isotropic interactions between electrons and…
Effect of electron-doping on spin excitations of underdoped BaFeNiAs
Leland W. Harriger, Astrid Schneidewind, Shiliang Li +8
We use neutron scattering to study magnetic order and spin excitations in BaFeNiAs. On cooling, the system first changes the lattice symmetry from tetragona…
Field-induced soft-mode quantum phase transition in LaSrCuO
J. Chang, N. B. Christensen, Ch. Niedermayer +13
Inelastic neutron-scattering experiments on the high-temperature superconductor LaSrCuO reveal a magnetic excitation gap that decreases continuously u…
Neutron diffraction on antiferromagnetic ordering in single-crystal BaFe2As2
Y. Su, P. Link, A. Schneidewind +9
Neutron diffraction experiments have been carried out on a Sn-flux grown BaFe2As2 single crystal, the parent compound of the A-122 family of FeAs-based high-Tc superconductors. A t…
